	Wait for event to complete.
template<Kokkos::ExecutionSpace ExecFrom, Kokkos::ExecutionSpace ExecTo>
void	Kokkos::Execution::Impl::impl_wait (const ExecTo &, const Event< ExecFrom > &event)
template<Kokkos::ExecutionSpace ExecFrom, Kokkos::ExecutionSpace ExecTo>

Variables
static constexpr auto	Kokkos::Execution::Impl::invalid_dev_id = Kokkos::Experimental::finite_max_v<uint32_t>

Detailed Description

Backends that support an event-like API specialize Kokkos::Execution::Impl::Event for their execution space type. The specialization must satisfy the Kokkos::Execution::Impl::event concept.
